SHADE-HOLDER.

Specification of Letters Patent.

Patented July 31, 1917.

Application filed February 9, 1916. Serial No. 77,276.

To all whom it may concern:

Be it known that 1, ROBERT K. \VITZ, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Shade-Holder; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification.

This invention relates to shade holders for electric lamp sockets, and particularly to those of the detachable type.

The object of my invention is the provision of an improved, simple, and inexpensive shade holder of the class described, which is capable of being easily and quickly applied to or removed from a lamp socket or having a shade applied to or removed therefrom, and which is also pleasing and attractive in appearance.

The invention is fully described in the following specification, and while, in its broader aspect, it is capable of embodiment in numerous forms, a preferred and a few modified forms thereof are illustrated in the accompanying drawings, in which,

Figure 1 is a side elevation of a shade-holder embodying the invention attached to a lamp socket and carrying a shade. Fig. 2 is a cross-section thereof on the line a900 in Fig. 1. Fig. 3 is a side elevation of a lamp socket, shade and shade-holder in separated relation and with the shade-holder in section and ready to receive the lamp socket and shade. Fig. {1 is a perspective view of the shade-holder with its lamp socket and shade receiving parts in open position. Fig. 5 is a central longitudinal section of a slightly modified form of the shade-holder. Fig. 6 is a perspective view of a filler strip which may be used. Figs. 7 and 8 are crosssections on the lines y z and w-c0, respectively, in Fig. 5. Fig. 9 is an enlarged fragmentary section on the line w-cv in Fig. 5, and Fig. 10 is an enlarged section on the line 41-41 in Fig. 5.

Referring to the drawings, 1 designates an electric lamp socket which is provided adjacent to its outer end with a circumferential bead or rib 2, as is customary with sockets of this character, and 3 designates a shade of any suitable type having an annular outwardly extending shoulder or bead t at its inner end.

The shade-holder in its preferred form, as shown in Figs. 1 to 4, comprises a body or skirt-part 5, which is contracted at its inner end to form the restricted neck portion 6 for receiving the beaded outer end of the socket 1, and has its outer end enlarged and forming the shade receiving edge portion 7, which is provided with a circumferentiallyextending recess T for receiving the shoulder or bead T of the shade.

The neck-portion 6 is of a size to fit quite closely around the outer end of the socket 1 and is provided with a circumferentiallydisposed recess 6 for fitting around or closely receiving the bead 2 of the socket. One side of the neck portion 6, for a portion of its depth, which is at least equal to the extent of projection of the socket 1 therein, is cut away or open, as at 8, to permit a transverse insertion of the socket end into or withdrawal from the neck 6, the width of the opening 8 being of suflicient extent for such purpose, as is apparent by reference to the drawings.

A retaining collar 9 is rotatably mounted on the neck portion 6, being provided with an internal recess which is complementary to and fits the bulged portion of the neck forming the recess 6*, thus preventing longitudinal movement of the collar on the shade-holder neck. The collar 9 is cut away at one side thereof to an extent corresponding to the side opening 8 of the neck portion 6, as shown at 10, and said openings 8 and 10 are capable of being placed into or out of register by a turning of the collar 9 on the shade-holder neck. dent that when these openings are in register the outer end of a socket 1 can be easily and quickly transversely inserted into or removed from within the neck portion 6, and that the collar 9 can be turned to place said openings out of register and to close the neck opening 8 to retain the shade-holder in engagement with the socket, as shown in Fig. 1.

The means employed for detachably secur- It is evior shade.

ing a shade to the shade-holder is similar to the means employed for attaching the holder to a lamp socket, and consists in rotatably mounting a collar 11 on the edge portion 7 of the shadeholder, said collar having a circumferentially extending internal recess complementary to the beaded part 7 of the holder, and providing the edge 7 and collar 11 with incuts or openings 12 and 13, respectively, which register when the collar is in one position and permit a transverse insertion of a shade edge l into or a withdrawal of the same from within the shade-holder recess 7. When the collar 11 is turned to close the edge opening 12 of the holder the shade is prevented from removal therefrom.

In Figs. 5, 7, 8, 9 and 10 the construction of the holder is slightly modified by disposing the socket and shade-holding collars within instead of without the respective edge portions of the holder, the construction otherwise being substantially the same. In this form 15 designates the body of the shade-holder, 16 and 17 the neck and outer edge portions thereof, respectively, 18 the neck collar, and 19 the base edge collar.

It will be noted in either form of the invention illustrated that the outer socket or shade embracing part of the shade-holder must necessarily be larger than the portion of the socket or shade which it embraces, due to the inner member or part fitting the socket If, therefore, it is found that looseness occurs between the shade-holder and socket or shade, a filler strip 20 may be inserted in the side opening of the inner member or part to turn therewlth within the outer part, as shown in Flgs. 5 and 7 to take a up any play or looseness.

" the finger being fixed at one end to the outer part as at 22, and being of sufficient length for its free end to lap the respective edge of the inner part when the two parts are in socket or shade-holdin relation, as shown in Fig. 8. The spring finger 21 is adapted and intended to cooperate with the opposed portion of the shade-holder to yieldingly grip and quite firmly hold the socket or shade, as the case may be, in the shadeholder.

I wish it understood that mv invention is not limited to a particular construction, arrangement or form of the parts as it is capable of numerous modifications without departing from the spirit of the claims.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is,

l. A shade-holder having an edge portion at one end provided with a side opening for permitting the transverse insertion into or removal of an article from within said edge portion, and a member slidingly carried by said edge portion and operable to open or close said side opening and to cooperate with said edge portion to retain an article therein.

2. A shade-holder having an edge portion at one end provided with a side opening for permitting transverse insertion into and removal of an article from within said edge portion, and a member carried for rotatable sliding movements by said edge portion and operable to open or close said side opening and to cooperate with said edge portion to retain an article therein.

3. A shade-holder having an article receiving edge portion at one end, and a member movably carried by said edge portion and adapted to cooperate therewith to retain an article therein, said edge portion and member fitting one within the other and having side openings which are movable into and out of register by relative movements of said portion and member and when in register permitting the transverse insertion of an article into or its withdrawal from within said edge portion and member.

a. A shade-holder having an article receiving edge portion, a collar rotatably mounted on said edge portion and adapted to cooperate therewith to retain an article therein, said edge portion and collar having side openings extending inward from their outer ends which are movable into and out of register by a relative rotation of said edge portion and member and when in register permitting the transverse insertion of an article into or its withdrawal from within said edge portion and collar through the 5 openings.

5. A shade-holder having an article receiving edge portion, a collar rotatably mounted on said edge portion, said collar and edge portion having complementary cir- 11o cumferentially extending bead receiving recesses fitting one within the other and adapted to cooperate to retain an article therein, said edge portion and collar having side openings which are movable into and out of register by relative rotary movements thereof and when in register permitting the transverse insertion of an article into or its withdrawal from within said edge portion and collar through the openings.

6. A shade-holder having a restricted socket receiving neck portion, a collar mounted on said neck portion, said collar and neck portion having oircumferentially extending complementary internal recesses and also having side openings extending inward a distance from their outer ends, said openings being movable into and out of register by a relative turning of the neck and collar and when in register permitting the transverse insertion of a socket into or its Withdrawal from within said neck portion.

7. A shade-holder having an outer shade edge receiving edge portion provided with an internal circumferentially extending shade edge receiving recess, a collar rotatably carried by said edge portion and adapted to cooperate therewith to retain a shade edge therein, said collar and edge portion having side openings extending inward a distance from their outer edges and movable into and out of register by a relative turning of the edge portion and collar and when in register permitting a transverse in sertion of an article into or its withdrawal from within said edge portion and collar.

8. A shade holder having a ring shaped part, a part telescopically and rotatably carried thereby, said parts each having a side opening for permitting the transverse insertion and withdrawal of an article from within said parts, when the openings are in register, and means disposed in the opening of the inner one of said parts to assist in securing the article in position.

9. A shade-holder having an edge portion formed with a semi-circular part projecting from said edge lengthwise of said holder, said part forming an internal recess extending from one end to the other thereof, a member rotatably carried by said edge portion of the shade-holder and having a part extending therefrom lengthwise of the shade-holder, with said part internally recessed from one end to the other thereof and adapted, when in one position with respect to said first mentioned part, to cooperate therewith to retain an article therein, and when in another position with respect to said part, to permit the transverse insertion of an article into, or its removal from, engaging relation to said parts.

In testimony whereof I have hereunto signed my name to this specification.
